Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
RBD SARS-CoV-2 HBsAg VLP Vaccine, administered at two dose amounts, 5mcg and 25 mcg, by intramuscular injection by Investigators (or delegate) during in-clinic visit. Phase 1 will include three cohorts, to receive either 5mcg dose on Day 0 and 28; 25mcg dose on Days 0 and 28 or placebo on Day 0 and 28.

Phase 2 will evaluate both dose amounts either as single dose (given at day 0, with placebo at Day 28) or two doses (at Days 0 and 28). Participants will be randomised into one of 5 cohorts. These are 1) 5mcg dose administered on Days 0 and 28; 2) 25mcg dose administered on Days 0 and 28; 3) 5mcg dose administered on Days 0 and placebo on Day 28; 4) 25mcg dose administered on Days 0 and placebo on Day 28, or 5) placebo on day 0 and 28.

Phase 2 will commence following DSMB review of safety data from Phase 1.

Two groups of participants will be enrolled. Phase 1 will include a group of healthy adults aged 18-45. Phase 2 will include a separate group of healthy adults aged 18 - 79 years.

Participants will return to site at day 7 and 14 from vaccine administration dates to undergo safety assessments and blood sampling for immunogenicity evaluation. Further on site assessments are conducted monthly or bi-monthly for up to 180 days from date of first vaccine administration.

Phase II; To assess the immune response of a two-dose schedule of two dose amounts of RBD SARS-CoV-2 HBsAg VLP vaccine as compared with two-dose administration of placebo in healthy adults aged 18 - 79 years as determined through changes in participant immunity 56 days from first dose. To assess the immune response following a single-dose schedule of RBD SARS-CoV-2 HBsAg VLP vaccine as compared with placebo in healthy adults aged 18 - 79 years as determined through changes in participant immune response 56 days after receiving the vaccine dose.
